FIELD OF THE INVENTION

The present invention is directed to a hair extension, a claspingmechanism for a hair extension, and a method of using the same.

BACKGROUND OF THE INVENTION

Various types of hair extensions are known. These hair extensions areused to give users who wear them the appearance of having different hairstyles or hair colors without the commitment of either having to growreal hair and/or having to dye one's real hair. In view of thesebenefits, hair extensions have gained widespread use.

However, conventional hair extensions need to be typically applied andremoved to and from a user's hair or scalp by a professional beauticianor hair stylist. This application and removal process results in aninconvenience and a high cost to the user.

Additionally, the conventional hair extensions are typically glued,sewn, and/or crimped to the user's natural hair and/or scalp. Thisapplication process results in discomfort and pain to the user and cancause damage to the user's natural hair and scalp.

Accordingly, a hair extension with an improved structure and attachmentmechanism is necessary to overcome these problems associated with theconventional hair extensions.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a hair extension 10 with a clasping mechanism 18according to an embodiment of the present invention. FIG. 2 is a topplan view of the clasping mechanism 18 of FIG. 1, and FIG. 3 is a crosssectional side view of the clasping mechanism 18 of FIG. 2, taken alongline A-A. Reference number 10 may refer to a body of the hair extensionwhich includes a plurality of hairs.

As best shown in FIG. 1, the clasping mechanism 18 is disposed at a topportion the hair extension 10 to be attached to hair on a user's head.The hair extension 10 includes a plurality of strands of hair 27. Theclasping mechanism 18 includes a first engaging part 14 and a secondengaging part 16 attached to the end (i.e., the top portion) of the hairextension 10. The first and second engaging parts 14 and 16 areconnected by a holding member 12 under which a line of a user's hair isreceived and clasped by the clasping mechanism 18. The holding member 12may be a wire or hinge. The first and second engaging parts 14 and 16may have a button-like configuration. As will be described below, theclasping mechanism 18 may be sewn into the hair extension 10.

The first engaging part 14 includes a coupling protrusion 20 extendingtherefrom in a direction away from the hair extension 10. The secondengaging part 16 includes a receiving recess 22 in which the couplingprotrusion 20 is received when the first and second engaging parts 14and 16 are coupled together by folding the top portion of the hairextension 10.

FIG. 2 illustrates the top portion of the hair extension 10 in moredetail. The first engaging part 14 and the second engaging part 16 mayhave bodies of a relatively flat circular shape. Alternatively, thebodies of the first and second engaging parts 14 and 16 may be made tobe a different shape (e.g., square, elliptical, etc). The first andsecond engaging parts 14 and 16 may be made of plastic, metal (e.g.,brass), or other suitable materials.

As best shown in FIG. 2, the first engaging part 14 includes peripheralholes (slits) 26 formed therein. These peripheral holes 26 are used tosecure the first engaging part 14 to the hair extension 10. Adescription of how the first engaging part 14 is secured to the hairextension 10 is as follows.

The hair extension 10 includes the hair strands 27 extending from top tobottom (i.e., vertically) in FIG. 2. For simplicity sake, only a fewstrands 27 of hair are illustrated below the clasping mechanism 18 inFIG. 2. However, it should be understood that these strands 27 of hairactually extend from top to bottom throughout the entire hair extension10. Here, a strand of hair can refer to a single hair or a plurality ofhairs.

Extension wires 25 are arranged among the strands of hair 27 in the hairextension 10. For example, the extension wires 25 may be wovenhorizontally in between the strands of hair 27. As illustrated in FIG.2, the extension wires 25 extend in a direction that is different fromthe direction in which the strands of hair 27 extend (e.g.,perpendicularly).

Attachment wires 24 couple the first engaging part 14 to the hairextension 10 via the peripheral holes 26 and the extension wires 25.That is, the attachment wires 24 are wound around both the peripheralholes 26 of first engaging part 14 and the extension wires 25 of thehair extension 10 to secure the first engaging part 14 to the hairextension 10.

As best shown in FIG. 2, the first engaging part 14 may have fourperipheral holes 26 that are diametrically opposed to each other.Alternatively, the first engaging part 14 may have any other number ofperipheral holes 26 provided that the attachment wires 24 caneffectively secure the first engaging part 14 to the extension wires 25.

The second engaging part 16 may have a similar arrangement as the firstengaging part 14. In particular, a body 16 of the second engaging partincludes peripheral holes 28 arranged around an outer periphery thereof.The second engaging part 16 is secured to the extension wires 25 bywinding the attachment wires 24 around both the peripheral holes 28 andthe extension wires 25.

The holding member 12 is wound around the peripheral holes 26 and 28 ofthe first and second engaging parts 14 and 16, respectively. A line ofhair (not shown) of a user is inserted under the holding member 12 suchthat the first and second engaging parts 14 and 16 of the claspingmechanism 18 are clasped together to maintain the hair line in position.Additionally, the hair line may be wound around the holding member 12one or more times for added security.

As can be seen in FIG. 2, the receiving recess 22 of the second engagingpart 16 is positioned to receive the coupling protrusion 20 of the firstengaging part 14 when the top portion of the hair extension 10 is folderover (i.e., when the top portions of the first and second engaging parts14 and 16 are brought together). The receiving recess 22 may furtherinclude protrusion maintaining wires 30 extending thereacross to engagethe coupling protrusion 20 when the coupling protrusion 20 is insertedinto the receiving recess 22.

As best shown in FIG. 3, the coupling protrusion 20 may have a bulbshaped head portion that increases in width from bottom to top. Theprotrusion maintaining wires 30 of the receiving recess 22 rest on the aportion of the coupling protrusion 20 where the bulb shaped head portionbegins increasing in width such that the coupling protrusion 20 cannotaccidentally release from the receiving recess 22 when the hairextension 10 is being worn by a user.

Additionally, the receiving recess has a graduated shape thatcorresponds to the coupling protrusion 20 in that the receiving recess22 increases in width toward a bottom thereof.

FIG. 3 illustrates the attachment wires 24 wound around the first andsecond engaging parts 14 and 16 through the respective peripheral holes26 and 28.

Arrow B in FIG. 3 illustrates the operation of the clasping mechanism18. The first engaging part 14 and the second engaging part 16 arebrought toward each other to couple the coupling protrusion 20 to thereceiving recess 22. In this manner, the top portion of the hairextension 10 is folded over and the line of hair of the user (not shown)rests between the hair extension 10, the holding member 12, and sides ofthe first and second engaging parts 14 and 16. The first and secondengaging parts 14 and 16 are hingedly connected to one another via theholding member 12.

For added security, adhesive may be applied to the receiving recess 22to adhere the coupling protrusion 20 therein.

The holding member 12 may be a nylon coated, multiple-strand stainlesssteel wire having a brass crimped bead disposed at ends thereof. Ofcourse, the invention should not be limited to this preferred materialas other suitable materials will be known to those of skill in the art.

Although the first and second engaging parts 14 and 16 are shown anddescribed as having the coupling protrusion 20 and the receiving recess22, it should be understood that this configuration is not intended tolimit the scope of the present invention. The coupling protrusion 20 maybe disposed on the second engaging part 16 instead of the first engagingpart 14, and the receiving recess 22 may be disposed on the firstengaging part 14 instead of the second engaging part 16.

FIG. 4 is a bottom plan view of the clasping mechanism of FIG. 1according to another embodiment of the invention. As can be seen in FIG.4, a bottom portion of the first engaging part 14 includes a crimpedbead 29 in which ends 29 a and 29 b of the holding member 12 aresecured. The crimped bead 29 is disposed in a recess in the bottomportion of the first engaging part 14 opposite to the couplingprotrusion 20 (not shown in FIG. 4). A bottom portion of the secondengaging part 16 has the protrusion maintaining wires 30, which may beconnected to an outer periphery thereof. As can be seen from FIG. 4, theprotrusion maintaining wires 30 extend across the receiving recess 22(not shown in FIG. 4) which has an outline 22′ represented by a dashedline.

FIG. 5 is a side view of the top portion of the hair extension 10 ofFIG. 1 when the clasping mechanism 18 is in a closed state. As can beseen from FIG. 5, the first and second engaging parts 14 and 16 areclasped together by the coupling protrusion 20 and the receiving recess22, respectively. For simplicity sake, the attachment wires 24, theholding member 12, and the extension wires 25 are not illustrated inFIG. 5. A space 30 is formed between the hair extension 10, the side ofthe first engaging part 14, and the side of the second engaging part 16.The line of hair (not illustrated) of a user is positioned in the space30 when the hair extension is being worn.

FIGS. 6A to 6D illustrate a method of applying the hair extension 10with the clasping mechanism 18 according to another embodiment of thepresent invention.

FIG. 6A illustrates a first needle 40 having a hole 42 and a movablelooping portion 44. The looping portion 44 is movable to open and closethe hole 42 such that a line of hair 48 can be disposed therein, asshown. Here, “line of hair” is used to refer to a plurality of hairsthat will support the hair extension 10 shown in FIGS. 1 to 5. The lineof hair 48 may simply be a section of hair (e.g., 1 mm in diameter),which is separated from the rest of the user's hair.

FIG. 6B illustrates the first needle 40 and a second needle 50. Thesecond needle 50 includes a hole 52. As can be seen in FIG. 6B, thefirst needle 40 having the line of hair 48 arranged in the hole 42 ismoved into the hole 52 of the second needle 50. The first and secondneedles 40 and 50 are made such that the first needle 40 can passthrough the hole 52 in the second needle 50. Once the hole 42 of thefirst needle 40 is moved through the hole 52 in the second needle 50,the line of hair 48 is maintained in the hole 52 of the second needle asshown in FIG. 6C.

FIG. 6D illustrates the second needle 50 being moved into position inthe clasping mechanism 18. As can be seen in FIG. 6D, the second needle50 is transferred between the holding member 12 and the hair extension10. Accordingly, the line of hair 48 is positioned between the holdingmember 12 of the clasping mechanism 18 and the hair extension 10 asshown in FIG. 6E.

At this point, the clasping mechanism 18 can be closed by engaging thecoupling protrusion 20 and the receiving recess 22 in the mannerillustrated in FIGS. 3 and 5. Alternatively, the line of hair 48 can bewound around the holding member 12 one or more times for added security,before closing the clasping mechanism 18.

It should be noted that although FIGS. 6A to 6E illustrate two needles40 and 50 used to position the line of hair 48 in the clasping mechanism18, a single needle may alternatively be used. For example, the firstneedle 40 shown in FIG. 6A may be transferred directly between theholding member 12 and the hair extension 10 once the line of hair 48 issecured therein.

FIG. 7 illustrates the hair extension 10 of FIG. 1 when it is being wornby a user 1. As can be seen in FIG. 7, the hair extension 10 and theclasping mechanism 18 is attached to the line of hair 48.

It should be noted that although FIG. 7 illustrates the outline of theclasping mechanism 18, the clasping mechanism 18 is not actually visibleduring use of the hair extension 10 (i.e., when the user is wearing thehair extension 10). Instead, the clasping mechanism 18 is disposed on aninner portion of the hair extension 10.

FIG. 8 illustrates a method of attaching the hair extension 10 and theclasping mechanism 18 of FIG. 1 to a user's hair according to anotherembodiment of the present invention. The method of FIG. 8 is describedbelow with reference to FIGS. 1 to 7.

First, a user collects the line of hair 48 at step S100. Here, the usermay moisten the collected line of hair to make the line of hair 48easier to manage.

Next, the user arranges the line of hair 48 in the first needle 40 atstep S110.

At step S120, the first needle 40 is then transferred through the hole52 in the second needle 50 such that the line of hair 48 is positionedin the hole 52 in the second needle 50.

Once the line of hair 48 is secured in the second needle 50, the secondneedle 50 is transferred along the hair extension 10 under the holdingmember 12 at step S130. The line of hair 48 remains in a hinge formed bythe holding member 12 and the first and second engaging parts 14 and 16.Also, in step S1130, the clasping mechanism 18 may be adjusted to adesired position on the root section of the line of hair 48. Theclasping mechanism 18 may be positioned so as not to be flush with auser's scalp.

At step S140, the line of hair 48 is wound around the holding member 12of the clasping mechanism 18 for added security.

At step S150, the clasping mechanism (clamping attachment) 18 is closedby inserting the coupling protrusion 20 of the first engaging part 14into the receiving recess 22 of the second engaging part 16. Here, theclasping mechanism 18 and the hair extension 10 lay flat on the user'shead.

At this point, the method of attachment of the hair extension 10 and theclasping mechanism 18 is complete. Now, the hair extension 10 may bepositioned and angled as desired on the user's head.

As set forth above, it should be noted that other variations of thismethod may alternatively be used. For example, the first needle 40 maybe applied directly to the clasping mechanism 18 without using thesecond needle 50. In this case, the steps S120 and S130 would becombined and modified to omit use of the second needle 50.

The method of FIG. 8 may be repeated for a plurality of hair extensions.

FIG. 9 illustrates a method of removing the hair extension 10 and theclasping mechanism 18 of FIG. 1 from a user's hair according to yetanother embodiment of the present invention. The method of FIG. 9 isdescribed below with reference to FIGS. 1 to 7.

First, in step S200, the clasping mechanism 18 is opened by removing thecoupling protrusion 20 of the first engaging part 14 from the receivingrecess 22 of the second engaging part 16. Here, side ends of the topportion of the hair extension 10 may be pulled apart from each other todisengage the clasping mechanism 18.

In step S210, a detangling agent is applied along the length of the lineof hair 48. The detangling agent may be PAUL MITCHELL® detangler. Thedetangling agent may be applied along the length of the line of hairincluding a root section thereof.

In step S220, a comb is run along the length of the line of hair 48.Here, the comb may be run along the length of the line of hair excludingthe root section of the line of hair 48. A fine tooth comb may be usedin step S220.

In step S230, the clasping mechanism 18 is removed from the line of hair48 by transferring the hair extension 10 along the line of hair 48 untilthe hair extension 10 is pulled from an end of the line of hair 48.

The method of FIG. 9 may be repeated for a plurality of hair extensions.

According to the embodiments of the present invention, the hairextension 10 can be applied and removed to/from a user's natural hair anunlimited number of times. This is due, at least in part, to the factthat the hair extension 10 need not be glued, crimped, or sewn to theuser's natural hair or scalp. The hair extension 10 can be worncomfortably by the user 1.

Additionally, the hair extension 10 may be applied and removed by theuser his or herself, without the aid of a beautician due to the easewith which the clasping mechanism 18 can be used.

The hair extension 10 may be made any length, color, or textureaccording to a user's needs.

Finally, the clasping mechanism 18 of the previous embodiments of thepresent invention secures the hair extension 10 to a user's hair suchthat the hair extension 10 can be worn during all different types ofactivity.
